Industrial aluminum surface after an oxidation, the appearance of the design is very beautiful, and dirty, according to different load-bearing structure using a variety of different requirements of the profile specifications, and the use of related supporting aluminum accessories, do not need welding, more environmental protection, and can be installed, disassembly, move is very convenient. Aluminum profiles
are widely used in the construction industry, with many unique excellent characteristics, low density, light weight, easy processing, corrosion resistance, non-magnetic, impact does not generate sparks, with high finish and brightness. Industrial aluminum is a kind of aluminum as the main component of the alloy material, aluminum rod through hot melting, extrusion to get different cross-section shape of aluminum materials, but the proportion of added alloy is different, the production of industrial aluminum profile mechanical properties and application fields are also different.
The higher the purity, the better the corrosion resistance, mainly because pure aluminum in the air and oxygen reaction, on the surface of aluminum to generate a thin and dense natural oxide film, faster and thicker than the oxide film of other metals, so as to prevent the further corrosion of harmful gases and water in the air, play a protective role.
Industrial aluminum profiles have high mechanical strength but low corrosion resistance. Although pure aluminum has good corrosion resistance, its poor mechanical strength restricts its application to some extent. Therefore, adding appropriate amount of magnesium, copper, zinc and other metals to aluminum to make various types of industrial aluminum profiles, greatly improve the mechanical strength of aluminum, expand its application range, but its corrosion resistance is worse than pure aluminum, so it may be oxidized corrosion. This requires powder coating to protect industrial aluminum profiles.
After the powder coating of aluminum profiles in addition to a relatively high corrosion resistance, but also has the advantages of diverse color design, good surface texture and many other problems, and a variety of product colors of architectural engineering exterior wall paint echo, to adapt to different architectural styles.
